+Subject: user32: Don't ignore return/error value of MapWindowPoints
+
+ScreenToClient should return zero if the operation fails, but is always
+returning TRUE. This patch corrects the problem and solves a crash bug
+in Lord of the Rings Online (bug #31979)
+
+Credit for discovering the source of this problem should go to somebody
+else, as yet unidentified, since the original patch came from a closed
+forum for beta testers of the LoTRO Riders of Rohan expansion and the
+forum has subsequently been wiped. However, I'll take credit for fixing
+it up, but if I ever figure out where it came from, hopefully they can
+get credit as well.
